The cost mostly. While we could build very well planned long term buildings, as a owner you care max about 1 or 2 lifetime (you, maybe your kids) so the premium to get it to last 10 generations isnt worth it. Mix with that governments elected to ease ownership access whatever you end up owning and the fact these old houses you talk abt were a sort of dick measuring multigenerational competition between rich bourgeois and you understand why we build what we need rather than what 3 generations down the line would have wanted us to pay the cost of so they dont have to.
